CVE-2022-35411
rpc.py versiones hasta 0.6.0, permite una Ejecución de Código Remota porque es producido un unpickle cuando es enviado el encabezado HTTP "serializer: pickle". En otras palabras, aunque JSON (no Pickle) es el formato de datos por defecto, un cliente no autenticado puede causar que los datos sean procesados con unpickle
CVSS
- Puntuación base

- 3.1
- Vector
- CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
